             Summary: Metadata Caching : min/max values are null for varchar columns in auto partitioned data
                 Key: DRILL-4070
                 URL: https://issues.apache.org/jira/browse/DRILL-4070
             Project: Apache Drill
          Issue Type: Bug
          Components: Metadata
    Affects Versions: 1.3.0
            Reporter: Rahul Challapalli
            Priority: Critical


git.commit.id.abbrev=e78e286

The metadata cache file created contains incorrect values for min/max fields for varchar colums. The data is also partitioned on the varchar column

{code}
refresh table metadata fewtypes_varcharpartition;
{code}

As a result partition pruning is not happening. This was working after DRILL-3937 has been fixed (d331330efd27dbb8922024c4a18c11e76a00016b)

I attached the data set and the cache file
